Many genes associated with the cell death such as tumour necrosis factor receptor (Tnfrsf1a), inhibitor of kappaB kinase (Ikbkg), kinases (Cd82 and Cdk2), and apoptosis regulator (Bcl2l1 and Birc2) were only up-regulated in WT infection and showed no expression in BM16 infection. The gene discussed is IKBKG; the disease is infection.
